🔍 Key Concepts

• Net Positive Suction Head (NPSH) definition and purpose • What causes cavitation in a centrifugal pump • How static head and system layout affect suction conditions

💭 Think About

• Ask yourself: when calculating NPSH available at the pump, which physical factors at the suction side change the pressure at the pump eye? • Think about the location of the feed pump relative to the DC heater and the water surface – what vertical distance matters? • Which answer choices are properties of the pump itself versus properties of the system supplying the pump?

✅ Before You Answer

• Identify which options describe system suction conditions rather than pump design characteristics • Confirm that NPSH includes vapor pressure of the liquid at pumping temperature plus (or minus) the effect of liquid level above/below the pump centerline • Check which choice directly relates to the static suction head from the feed system (like a DC heater or hotwell) to the pump inlet
